METALLIC BRUSH CLEANER.

Application filed March 30, 1922. Serial No. 548,266.

To all whom it may concern.

Be it known that l, JOSEPH FRITZ, citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Metallic Brush Cleaners, of which the following is a specification, reference being; had therein to the accompanying drawings.

This invention relates to brush cleaners and it has for its object to provide a device of simple and inexpensive construction which will serve to e'lliciently clean brushes of various kind.- The device of the invention is particularly intended and adapted for cleaning brushes of carpet sweepers. It is a well known fact that these brushes become clogged with hair, pieces of string, lint and the like to such an extent as to seriously interfere with their proper functioning. The article of the present invention serves to rapidly and eiliciently clean such brushes. It will also clean brushes of any kind the bristles of which have strands, such as hairs, string or the like entangled in them.

The figure shown in the accompanying drawing is a perspective view of a carpet sweeper brush cleaner constructed in accordance with the invention.

The article constituting the subject matter of the present invention comprises a shank or handle 5, laterally extending curved teeth 6 at one side edge thereof and adjacent one end thereof and a rearwardly directed hook or prong 7 formed at the opposite side. The article as a whole is stamped from sheet metal and manufactured with great rapidity and at a very small cost.

It is a well known fact that in many brushes the bristles are arranged in rows leaving passages between them. in brushes of this character the rearwardly directed hook 7 may be raked along such passages removing; the heaviest of the obstructions and loosening the remainder to such an eX- tent that when the teeth 6 are raked laterally through the brushes the remaining foreign material is readily dislodged and removed.

It is to be noted that the metal of the article is cut away at 5 in such manner that the hook 7 may lie within the width of the handle proper. This serves the double purpose of forming a considerable recess for the reception of the strands to be removed and of reducing the cost of manufacture. If the hook 7 were disposed outside of the line of the upper edge of the handle it would result in the waste of a strip of metal equal to the length of the handle and equal in width to the height of the hook for each cleaner manufactured.

It is to be understood that the invention is not limited to the precise construction, set forth but that it includes within its purview whatever changes fairly come within either the terms or the spirit of the ap pended claims.

Having described my invention what I claim is:

1. A device of the character described comprising a handle having a plurality of teeth projectingfrom the side edge thereof adjacent one end, said teeth being curved laterally beyond the plane of the handle.

2. A structure as recited in claim 1 in combination with a rearwardly directed hook at the end of the handle.

3. A structure as recited in claim 1 in combination with a rearwardly directed hook at the end of the handle and at that side of the handle remote from said teeth, said hook lying wholly in the plane of the handle.

4:. A device of the character described stamped from sheet metal and comprising: a fiat handle having a plurality of curved teeth projecting downwardly and laterally at a side edge thereof adjacent one end thereof and a rearwardly directed hook lying wholly in the plane of the handle and located at the same end of the handle as the teeth but at the opposite side of the handle.

In testimony whereof I hereunto my signature.

JOSEPH FRITZ.
